Apple A18 Pro Outpaces A17 Pro by 13% in GFXBench’s Aztec Ruins Benchmark, But Efficiency Takes a Hit

The A18 Pro, the powerhouse behind Apple’s latest iPhone 16 Pro and iPhone 16 Pro Max, has already garnered attention for its impressive speed, clocking in at 18% faster than last year’s A17 Pro in Geekbench 6’s Metal benchmarks. It even goes toe-to-toe with the M1 chip in both single-core and multi-core performance. But the real question is, at what cost? In the latest GFXBench Aztec Ruins test, this cutting-edge System on Chip (SoC) hits new performance highs, but with an important caveat – it requires more power, leading to a less efficient ‘performance per watt’ ratio compared to its predecessor.

In the demanding GFXBench Aztec Ruins benchmark, which pushes the GPU to its limits at a 1440p resolution, the A18 Pro demonstrated a power draw of 11.5W. This is a notable increase from the A17 Pro’s consumption of 9.72W. While the A18 Pro manages an impressive framerate of 72FPS – a 16% improvement over the A18 and 13% faster than the A17 Pro, which clocked in at 62FPS and 64FPS respectively – it achieves these gains at a cost of higher power usage.

Digging deeper into the data, it’s clear that the A18 Pro’s performance boost comes with a trade-off. One of the benchmark graphs revealed that despite being made with TSMC’s second-generation 3nm process, the A18 Pro has a lower ‘performance per watt’ ratio than its predecessor. This indicates that Apple might be allowing the chip to run at full throttle to score higher in benchmarks, albeit at the expense of increased power consumption.

By performing a simple division of the framerate by the power consumption, it becomes evident that while the A18 Pro delivers top-tier performance, it’s not as power-efficient as the A17 Pro. This could be due to Apple’s decision to push the silicon harder, potentially enabled by the improved thermal designs of the iPhone 16 Pro and Pro Max, which allow the chip to safely operate at higher power levels.

It’s worth noting that benchmarks like GFXBench are built to stretch a chipset to its maximum potential, so the A18 Pro’s higher power consumption might not be a factor during typical smartphone use. However, this does provide an intriguing glimpse into how the SoC will behave under the strain of AAA gaming, where enhanced performance and better thermal management could prove beneficial despite the increased power draw.

In summary, the A18 Pro’s performance is undeniably impressive, setting new benchmarks for speed and capability. However, this performance comes with a heavier power demand, resulting in a less efficient performance-to-power ratio. As we continue to push the boundaries of smartphone technology, balancing performance with power efficiency will remain a crucial challenge for future innovations.
